I have two Windows XP computers, at the moment they are networked by a purple cable that means we dont need a hub. We share the internet connection, our older computer is linked to the new one, which has the internet connoection, and the internet works on the older computer. However, we want to get rid of the wires and link them wirelessly. Can somebody please tell me the cheapest, easiest way, that will let us keep sharing the internet connection?
